IMPROVEMENT IN LATHES FOR TURNING OVALS.

Specification forming part of Letters Patent No. 168,928 dated October19, 1875; application filed September 25, 1875.

To all whom it may concern Be it known that I, LOUIS K. ScoTEoRD, ofBurlingame, in the county of Osage and State of Kansas, have invented anImprovement in Lathes for Turning Ovals, of which the following is aspecification:

My improvement consists of a sliding plate in the revolving disk havinga slot, in which is a stationary stud, placed eccentrically to the axisof the disk, causing the slide to work forward and backward-in the disk,the said stud being attached to a stationary center, around which thedisk revolves, and being adjustable toward and from the axis of the diskto vary the movements of the slide, as required, for making ovals ofdifferent forms.

Figure 1 is a front elevation of my improved oval-turning lathe, andFig. 2 is a horizontal section taken on line 00 w of Fig. 1.

Similar letters of reference indicate corresponding parts.

A A are the revolving cone-pulleys, turning on the stationary center B,and having the face-plate C fitted in its face, so as to slide freelyforward and backward. This slide, which is to carry the work, has aslot, E, which works on a stud, F, projecting from the stationary centerB, and being attached thereto by the slotted arm G and bolt H, so thatit can be shifted toward and from the axis. This causes the plate 0 toslide, more or less, according to the distance the stud is LOUIS K.SUOTFORD. Witnesses:
